Ti , No Spark??

[Paul S.]

Car Ran Fine (66, 425hp)came Home Shut It Off. Now It Has No Spark. Tried A New (current Replacement Ti Box Module) Still No Spark. Also Checked Connections Etc. Could It Just Be The Coil? . I Know I Can't TRY A Non Ti Coil On A Ti Car , But Can I Try This Coil(ti) On A Non Ti Car And See If The Ti Coil Is Bad ??? I'VE GOT A COUPLE NON TI CARS I COULD TRY THE COIL ON BUT THE 425 CAR IS THE ONLY TI CAR I HAVE .

Try this link. I posted a GM/Delco test procedure for TI ignition some time ago.

Check the ohms resistance on the PU coil, if 0, then it's probably open and your culprit.

I had a similar problem on my 67 small block TI, and it turned out to be a bad ground at the amplifier box. Removed the box, cleaned all ground connections and it runs perfect.

Paul,
Make sure, where the engine wiring harness attaches at the firewall, is secure, clean , and a tight fit.
